I have sent the following to Sansas Technical Support and would like to
thank you all for your suggestions. Especially Lars and Mark, and North
Star, for taking the time to give me the key sequences for selecting MSC
from the settings menu.

" I took delivery of a Sansa E280 Factory Reverb today. I am unable to boot
the device in MSC mode. It will boo to MTP mode.
